Wisport ZipperFox 40 Backpack — RAL 7013

The ZipperFox 40 is a 40-litre pack developed by Wisport for field use in demanding conditions: technical hiking, hunting, logistical support, and professional outdoor operations. Measuring 60x29x25 cm with an empty weight of 1,850 g — barely more than a litre and a half of water — it offers a generous volume without loading you down before you've even packed it.

The SAS suspension system is where Wisport focused the ergonomic design: elongated shoulder straps shaped to follow the spine work together with the removable aluminium stay and detachable hip belt to transfer the load onto the hips when terrain and pace allow. Remove the stay and hip belt and you get a more compact, lighter pack for fast movement or transit. The shoulder straps include an adjustable sternum strap to stabilise the load laterally. The external MOLLE webbing lets you attach compatible pouches and accessories without altering the main structure; the internal MOLLE panel offers the same modularity inside the main compartment.

The U-shaped opening on the main body gives access to the contents from three sides, bringing the ergonomics closer to a rigid bag than to a traditional top-loading pack — useful when you need something from the bottom without emptying everything out. The 7 internal pockets and dividers keep your gear organised. The double bottom houses a built-in rain cover ready to deploy. The ID panel, CamelBak-compatible, takes a hydration bladder (not included) with a routing port for the drinking tube. Quick-release ski attachments round out the feature set for winter mountain use.

Key features

• Three-sided U-shaped opening: direct access to contents without unpacking the bag, even in low visibility or with gloves on.
• SAS system with removable aluminium stay and detachable hip belt: adapts to your pace, shifting weight onto the hips when needed or stripping down for fast movement.
• Internal and external MOLLE: expandable with compatible pouches without upsetting load balance.
• Integrated rain cover in the double bottom: always there when you need it, takes no space in the main compartment, and can't be left at home.
• Wisport zippers and ITW Nexus/Duraflex buckles: hardware chosen for reliability in harsh environments, not interchangeable with budget equivalents.
• CamelBak-compatible hydration sleeve: on-the-move hydration without removing the pack, with a dedicated internal ID panel.
